To LIZ 1071/0712/ U; '/.Imfg/ concern:

Beit known that l, JAMES II. CLARK, a citizen of the United States,residing at Portage, in the county of Columbia and State of Wisconsin,have invcu ted certain new and useful Improvements in Railway-Signals;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, suoli as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in signaling devices, moreparticularly for railroads at street-crossings, bridges, junctions, orother danger-points. It provides for guarding against accidents, as arevery liable to occur at said points, and to effect the automatic settingof the brakes of a train upon its approaching the place of danger,whether it be moving slowly or rapidly or forward or backward, toprovide for the simultaneous actuation of a bolt, as may be employed ata bridgedrawer with the setting of a signal, and to readily operate oradjust the parts or mechanism in setting the signal.

It consists of sundry combinations and arrangements of parts, including`their construction, substantially as hereinafter more fully disclosed,and particularly pointed out by the claims.

In the accompanyingdrawings, illustrating the preferred embodiment of myinvention, Figure l is a plan view thereof. Fig. 2 is a longitudinalsection. Fig. 3 is a transverse section taken on the line fc of Fig. l,with the air-brake-setting-valve-actuatingcontrivance orshoe in endelevation. Fig. 4 is a side elevation with theair-brake-setting-valve-actuating contrivance or shoe as adjusted forengagement with the signal apparatus or device. Fig. 5 is a brokenlongitudinal sectional View with the signal for clean Fig. 6 is anenlarged detail view of the air-brake-settingvalve-actuating contrivanceor shoe proper in vertical section with a port-ion of the air-valveremoved, disclosing the ports thereof. Fig.

7 is an enlarged detail section taken through said valve at right anglesto the section of the last-referred-to gure.

Latitude is allowed herein as to details, as they may be changed orvaried at will without departing from the spirit of my invention and thesame yet remain intact and be protected.

in carrying' out my invention I suitably arrange, preferably in anexcavation under and transversely of a railway-track, as shown, ahorizontal rock-shaft l, hung or journaled in a suitable manner upon thelower side, preferably, of a plate or platform 2, adjacently to astreet-crossing, junction, bridge-drawer, or other danger-point. Saidhorizontal shaft has geared thereto by suitable gearing 3a 3 a verticalor upright shaft 3, journaled in a suitable bearing or support et,screwed or otherwise fastened in place, preferably upon the plate orplatform 2. Said upright shaft carries the usual conventional signal,comprising a disk 4f and a lantern 4", having bull"- eye lenses, saiddisk being red and two of the lenses being of a corresponding color andfacing in the same direction as said disk and the other two lenses ofsaid lantern being plain glassl and facing at right angles with saidcolored lenses. Said horizontal shaft l has fixed thereto two camprojections orlugs 5,arranged to occupy positions upon opposite sides ofthe track, respectively,and having their free ends preferably extendedslightly laterally, the plate or platform 2 having openings 5 52L topermit the movement therethrough of said lugs or projections as they arethrown up or depressed, as presently more fully referred to.

Cam plates or levers G are suitably pivoted or hinged alongside of thetrack, preferably by bending or curving upward one end of each into aneye 6, which receives a pintle 6b, preferably lixed in eye-endedterminals 6c or plates 7, secured or screwed to the rail-ties. The sameends of the plates 7 may have preferably brazed thereto upon the underside the lower ends of npturned metal pieces 8, overhanging the pivotedor hinged ends ofthe levers or plates 6, beneath which extend theterminals of the eyes 6n of said levers or plates and which serve tohouse the pivotal points of the last-named and to form stops against thepossible upward displacement of these levers. The free ends of saidlevers or arms are preferably curved slightly downward to permit inbacking of the car or train when the signal is set the ready passingthereon of the brake-setting shoe or contrivance.

likewise forked or bifurcated and embracing' and pivoted to a pendentlug 13 of the block or coupling 10. Said link 12 may be and ispreferably -passed through an opening invoneA of the brackets 9, thesame thus acting as a guide thereto during movement.

To one end of the slide or rod 8, having, preferably, an aperturetherethrough, is connected one end of a cable or wire 14, its connectionor fastening to said rod or slide being aided by said aperture and ispassed over a pulley or wheel 15, hung in a suitable support or bracket16, preferably seeuredto a plate` or base-piece suitably anchored orembedded in place. Said cable or wire is connected at its opposite endtoa hand-lever 15, pivoted a short distance from its lower end to asuitable support 16', suitably secured in place, and to said end of saidlever is connected one end of another wire or cable 17, whose oppo-vsite end is connected to the other end of said slide or rod 8,preferably having an additional aperture therethrough for aiding thesecuring of said cable or wire thereto. Said support 16 is preferablycomposed of duplicate upper yend-curved frames or quadrants 16a, betweenwhich the handlever 15a is arranged and which have their curved orarcuate portions provided with coincident or registering apertures 1Gb,through which and an aperture in said hand-lever may be passed theshackle or bolt of. a padlock or other suitable fastening in lockingsaid lever in place to prevent unauthorized movement thereof; also,suitably connected, as presently disclosed, to the hand-lever 152l is abolt or latch 18 for engagement with a keeper 18a, secured to abridge-drawer, whereby simultaneously with the throwing of the signaldevice said drawer-bridge is locked and unlocked, as Will be presentlyunderstood. Said bolt or latch, preferably cylndrical,`has a cross-pinfixed therein, the projecting ends of which' form stops to limit themovement of said bolt, said cross-pin engaging the bolt-housing 18b andthe upstanding parallel supports 18c for that purpose, both said housingand supports being brazed or cast with a base-plate. To the rear end ofsaid bolt, with which is brazed or cast upon its upper surface abifurcated or slotted extension S, is connected a centrallypivoted lever19, fulcrumed between supports 18c at theirl upper ends. Said connectionis effected by a pin 18, spanning the space between and fixed on thebrackets or arms of the bolt extension 18d and engaging or passingthrough an elongated slot 19@L of the lever 19, said lever beingreceived between said arms or branches and said slot allowing therequisite differential movement between the parts, as will beappreciated.' The connection between the hand-lever 15 and said latch orbolt is effected 'as follows: Two wires or cables 2O 20 are connectedone to the extreme rear end of the bolt extension 18d and the other tothe upper end of the lever 19, each preferably having an aperture to aidin effecting this connection. Said wires or cables are then extendedback and connected to said hand-lever 15 at points upon opposite sidesof its pivot or fulcrum.

Suitably arranged and connected to the airbrake-setting valve 22,located upon the engine-frame, is a contrivance or shoe 23 for actuatingsaid valve, as presently explained. Said valve comprises a cylinder orchamber 22, preferably circular, communicating with the train air-brakepipe and having the usual air-ports, and within this chamber is arrangeda central valve stem or spindle 22", turning therein, its inner endbearing in a central seat or socket in the inner wall of said chamber.Said spindle or stem has fixed to it a disk or valve proper, 2, havingports therethrough corresponding with the ports in the chamber 22, saidstem or spindle also bearing or passing through the outer head 22d ofsaid chamber or cylinder adapted to be screwed in place. The outer orprojecting end of the spindle or stem 22b carries an arm 23, fixedthereon preferably by a pin passed therethrough. To the outer or freeend of said arm is pivoted or loosely connected the upper end of a link23, let into a slot 23b in a bar or slide 24C and pivoted to said bar orslide. Said bar or slide is preferably equipped at its lower end with awheel of shoe 24, adapted in practice to ride upon or be engaged byeither of the pivoted or hinged cam levers or plates, according to theside of the engine upon which it may be arranged. Said bar or slide ishoused and moves in a casting or tube 25 integral or cast with theoffset portion of a bracket or plate 25% suitably secured to theframework of the engine, and to which is also connected thevalve-casing, the same also affording a convenient means for theattachment thereof to said framework. Said bar or slide has preferablycast therewith upon its forward edge a plow attachment 26, reaching downsufficiently to guard the shoe or wheel 24: and to remove snow, dac., infront thereof, as in the winter season, when the train is in motion. Thetube or casing 25 has a longitudinal slot 27 through its front portion,into'which the forward edge of the bar or slide carrying the plowattachment extends, permitting said edge to stand flush with the outersurface of said tube or casing and said plow attachment to occupy a IOSIIO

comes position outside of said tube or casing. Said bar orslide haslateral vertical extensions or guides 28, extending into correspondinglateral slots 2S, produced in the tube or casing 25, one of saidextensions or guides having upon its outer surface a ratchet or seriesot' notches, with which automatically engages a spring pawl or detent29, carried-by said tube or casing and normally engaging' said ratchetto retain the slide or bar 2st elevated after having been acted upon b ya cam arm or lever 6 as presently seen. The tube or casing 25 has alsoin its rear side, opening through the lower end or edge thereof, a slot30, which with the corresponding portion of the slot in the front sideof said tube or casing provides for the reception of the wheel or shoecarried by the bar or slide 2l as it is raised to its maximum altitude,as when acted upon by a contacting cam plate or lever 6.

In operation, it being assumed by way of one example of illustrating theoperation of the invention it is required, for instance, to open abridge-drawer, the hand-lever is inanipulated or adjusted and locked insuch position so as to set the signal to danger, displayingr the reddisk and corresponding lenses of the lantern for use at night in thedirection of the line of travel, the drawerbolt at the same time beingwithdrawn ordisengaged froin its keeper; also, simultaneously with thesetting of tho signal, dac., the horizontal or rock shaft will beactuated so as to dispose by the action of its lugs or cams the camplates or levers in an inclined position. Should even the engineer of anapproaching train not happen to discover the displaying of thedanger-signal and not open the brake-setting valve, the inclinedcamplates would intercept the shoe or wheel equipped slide or bar andeffectits elevation, and thus be maintained by the spring pawl or detentcarried by the inclosing casing or tube of said bar or slide. Thisaction of the cam-plate upon said slide or bar will actuate theair-brake-setting valve and result in the application of thetrain-brakes, causing the slowing down and duly stopping of the train,thus avoiding what would otherwise have ended in a wreck and in allprobability the maiming of limbs, loss of life, and destruction ofproperty or rolling-stock. Of course after the closing of the drawer thesignal can be set for clear by oppositely or reversely adjusting thehand-lever, when the horizontal rock-shaft will be so actuated as todepress its cams or lugs, permitting the lowering of the cam-platesflush with the groundsurface or plate containing the same; also, thedrawer-bolt will be projected into its keeper, effecting the locking ofthe drawer against unauthorized opening, the hand-lever being alsolocked in position.

lt is observed that this device is applicable for use in connection withwhat is known as the block system, as well as generally in devices ofthis character.
